Dirt Map Scaling issue?

[Mugz]

Hi,

I’m having an issue with the dirt map and getting it to show the way I want when I adjust the scale of the geometry.

In the (good/green) image you will see that at roughly 200cm the dirt map is showing up (the way I want) but then when I scale the object down to 2cm (20mm) I cannot get the dirt map to look the same no matter how much I play around with the dirtmap sliders?? I’ve tried every combination for the past hour trying to get them to look the same but can’t?

Any guidance/solutions would be very much appreciated.
Thanks!

Have you tried to scale radius too?

I did thank you. Like I said I messed with the dirt map sliders (which there are only something like 5) for an hour and could not achieve the same coverage on the larger scaled model...

Got it sorted! I had to change the ray epsilon from .0001 to .000001 and the dirt map worked correctly. Hope this helps someone.
